AUTOMATIC SLIVER IND BROOKLYN, NEXV YORK.

ICATOR AND RECORDER.

SPECIFICATION forming part of Letters Patent No. 549,444, dated November 5, 1895.

Application filed April 27, 1895.

To all whom it may concern.-

Be it known that I, OAROLUS E. DAILEY, a citizen of the United States, and a resident of Brooklyn, Kings county, New York, have invented an Automatic Sliver Indicator and Recorder, of which the following is a specification.

The object of my invention is to construct a device which will automatically indicate and record the character of slivers or yarns passing from or to or through textile machinery in which the slivers or yarns are being prepared.

lWIyinvention is more particularly applicable in connection with the delivery-rolls of preparing machinery generallysuch as breakers, spreaders, drawing-frames, and condensers-for hard fibers,such as for bindertwine, or breakers and condensers for soft fiberssuch'as woolen, cotton, jute, &c.

In the accompanying drawings I have shown my invention as applied to the delivery-rolls of a machine known as a finisher for hard fibers.

Figure 1 is an end View of the machine, showing my improvements as applied; Fig. 2, a side View of the end of the machine, and Fig. 3 a plan View.

A A are the side frames of the machine, upon which are mounted the housings A for the'bearings a a of the shafts lib. of the delivery-rolls B B, which are geared together at C and may receive rotary motion in any suitable way, as through a belt-pulley applied to the extended end b of the lower shaft 1). These delivery-rolls are what are known as male and female rolls, the upper rollB being in the form of a disk working in a groove in the lower roll B, and the sliver from the machine is fed by the two rolls through this groove. The bearings for the shaft of the upper delivery-roll are acted on by springs E, whose tension can be adjusted by suitable screws 6, and which tend to keep the upper roll in contact with the lower roll. Nevertheless, the upper roll will rise or fall to a greater or less extent accordingto the inequalities in the sliver or yarn passing through, and I avail myself of this movement to secure an indication and record of the condition of sliver or yarn passing to or through the pre paring machinery.

Serial No. 547,298. (No model.)

I mount upon the housings A A or other suitable part of the frame of the machine a cross-beam F, in which I provide vertical guides f f for a saddle-piece G, which is mounted upon and will rise and fall with the shaft of the upper roll B. This saddle-piece has a pin or projection g projecting up through an opening f in the cross-beam F and serves to transmit motion to the indicating and recording devices.

The indicating mechanism may be adapted to give both visible and. audible signals, and these signals may be at the machine or at a distanceas, for instance, in the oflice of the factory where the machinery is running. In the drawings I have shown an indicator device H, consisting of a dial h and pointer 72, mounted on the machine, and in connection with this I have shown in diagram electric circuits to cause the sounding of audible signals h 71 at the machine and h h at a distance, as in the office of the factory, when extreme conditions of too great thickness or thinness or unevenness of the sliver or yarn happen.

The pivoted pointer h is acted upon at its lower end by an adjustable collar c on a horizontal rod I, guided at one end in frames 7o 011 an extension of the cross-beam F and at the other end having a pivotal connection with a bell-crank lever J, which is pivoted to the cross-beam, and has its lower arm acted on by the projection g of the saddle-piece G. A spring i tends to keep the lower arm of the bell-crank lever J in contact with the projection of the saddle-piece G.

For operating the audible signals electricity may conveniently be employed. For that purpose two insulated contacts 3 and 4 may be provided upon the indicator-plate h, the contact 3 being connected through a conductor 5 with a return-conductor 6, containing a battery and leading to a contact 8 on the pointer h, while the contact 4 is connected through a conductor 7 with the same return-conductor 6, which is thus common to both circuits. In the circuit of the conducother audible signals k at the machine and 71 at a distance, while in the circuit of the conductor 7 there may be provided other and different sounding-signals 7L and If, so that tor 5 there may be provided electric bells or extreme conditions of the sliver will be audibly announced, as before explained, when the pointer 7L comes in contact with either the stop 3 or the step ii.

I will now explain, in connection with the drawings, the construction of a recording device which may be used in carrying my in Yen-- tion into effect, although other forms of recordin devices may be used. Upon the same rod I which actuates the indicating mechanism already described I mount a stylus, pencil, or other marking device. I have shown a stylus S, which may be arranged in the vertical position shown and be simply guided in a vertical socket or sockets in a collar 5, carried by the red I. Under this stylus or pencil I cause to be fed at a relatively-slow speed adisk or sheet of any suitable material. If a stylus is used, a disk or sheet of foil or other such soft metal may be used to receive the impression due to the weight of the stylus, and if a sheet is employed it may be supplied from a roll and fed through pairs of feed-rolls K and K, mounted in hearings in the plates or frames 7,, hereinbefore referred to. These feedrolls for the record-sheet may receive their motion through any suitable mechanism. In the drawings I have indicated a convenient construction, consisting of an inclined shaft m, having at one end a worm-wheel m, driven by a worm b on the shaft Z) of the lower feed-roll, while at the other end of the shaft in there is a worm m, engaging with a worm-wheel m on the shaft of one of the feed-rolls K.

I claim as my inventioni. In a textile preparing machine, the combination of male and female rolls, through which yarn or sliver passes and yielding bearings in which the shaft of one of said rolls is mounted, with a cross-beam, a saddle piece resting upon said shaft, and guided in said cross-beam, and an indicator mechanism having its movable parts actuated by said saddle-piece, substantially as described.

2. In a textile preparing machine, the combination of male and female rolls through which yarn or sliver passes, and yielding bearings, in which the shaft of one of said rolls is mounted, with a cross-beam, a saddle piece resting upon said shaft and guided in said cross-beam, and a recording mechanism having its movable parts actuated by said saddle-piece, substantially as described.

3. In a textile preparing machine, the combination of rolls through which yarn or sliver passes, and yielding bearings in which the shaft of one of said rolls is mounted, with a cross beam, a saddle piece bearing upon and moving with said yielding shaft, and guided in said cross-beam, a rod adapted to control the indicating and recording mechanism and a bell'crank lever connected to the said rod and actuated by the said saddle'piece, substantially as set forth.

4,. In a textile preparing machine, the combination of rolls through which yarn or sliver passes and yielding bearings in which the shaft of one of said rolls is mounted, with asaddle piece bearing upon and moving with said yielding shaft, a bell-crank lever acted on by said saddle piece, a horizontal rod, carrying a recording instrument, an indicator pointer acted on by the said rod and a spring to act upon the pointer and through it upon said rod, substantially as described.

5. In a textile preparingmachine, the combination of rolls through which yarn or sliver passes and yielding bearings, in which the shaft of one of said rolls is mounted, with a cross beam, a saddle piece bearing upon and moving with said yielding shaft, and an audible alarm controlled by said saddle piece, substantially as described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
